LD Products HP 45 51645A Replacement Ink Cartridges Black 9-Pack

Nine-pack black cartridges for legacy HP printers

This nine-pack supplies nine black ink cartridges that replace the HP 45 51645A model. They are built for owners of older HP DeskJet, OfficeJet, PhotoSmart and DesignJet printers who need a low-cost way to keep those machines running. The dye-based ink is formulated for everyday document printing rather than archival photo work. Buyers who want colour output or high-capacity tanks should look elsewhere.

Consistent output across a full print run

Each cartridge is rated for approximately 1100 pages, so the pack covers a large volume before any replacement is needed. Because the ink is dye-based, density stays steady from the first page to the last without the settling issues sometimes seen with pigment formulas. The remanufactured shells are tested to prevent streaks or clogged nozzles during extended sessions. Users who require pigment durability for water-resistant prints will not get that characteristic here.

Verify the exact printer model before ordering

The compatibility list includes dozens of specific model numbers such as DeskJet 950C, OfficeJet G85, PhotoSmart P1000 and DesignJet 750c Plus. Check your printer’s label against that list; similar-sounding names like DeskJet 952C or OfficeJet Pro 1150Cse are included, but later series are not. No firmware updates or chip resets are mentioned, so assume the cartridges must be recognised by the original printer electronics.
